How do I use google drive?

Google Drive lets you experience hassle-free file management that uses file storing and sharing of all your work. With your information stored securely in the cloud, you can access your files at ease whenever and wherever you need it, on any device! You can also share that data easily with anyone through easy-to-manage sharing controls. Google Drive works with other Google Apps you already use, and even Microsoft Office as well as over 40 popular file formats. You’ll never have to worry about big file attachments with a 30 GB free storage space per user with an option to upgrade to Unlimited Storage.
